Oura is reportedly preparing an initial public offering as soon as September that could value the Finnish wearable maker at more than $16 billion, according to a TechCrunch report. The company has not confirmed the timing or the target valuation. An offering on that schedule would leave little public runway before any filing.

Oura’s main product is a smart ring that estimates sleep, activity and recovery, sold with a subscription for deeper analytics. The form factor has set the company apart from wrist-based rivals such as Apple and Garmin. The ring has drawn customers who want continuous health data without a visible watch.

A debut above $16 billion would rank among the larger consumer-health listings of the current cycle.

A debut above $16 billion would rank among the larger consumer-health listings of the current cycle. Public investors have been selective with hardware companies, often favoring those that can show durable subscription revenue. Oura’s mix of devices and software would be a central question if the company proceeds.

The report arrives as more technology companies test public markets after a quieter stretch for new listings. Any IPO would still require regulatory filings and market conditions that are not yet in evidence. Until those documents appear, the September timeline and the valuation remain unconfirmed.
